    Attempt to slightly refine the print out from "show alllocks" -- list
    the process and thread numbers/names on the same line rather than on
    separate lines, and print the thread pointer not just the tid.

    Add "show alllocks" command to DDB, which dumps a list of processes
    and threads currently holding sleep mutexes (and spin mutexes for
    curthread).  This can be quite useful in looking for a lock condition
    summary for a system, as it avoids manually iterating through threads
    and processes to find all the interesting locks.
  
    NB: "alllocks" is up there with "lockedvnods" for a bad argument for
    show.
